Fixed by HADOOP-5247
> Reducers continue to run even if a job failed.
> ----------------------------------------------
>
> Key: HADOOP-5609
> URL: https://issues.apache.org/jira/browse/HADOOP-5609
> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.18.3
> Reporter: Qi Liu
>
> When a job failed, in rare case, some reducer slots are not freed (continue
> to try collecting data even if the job is not running). These occupied
> reducer slots are not usable by following mapred jobs unless the task
> trackers are restarted.
> These reducers continue to report the progress to job tracker, which results
> the following logs:
> 2009-03-31 23:59:59,992 INFO org.apache.hadoop.mapred.JobTracker: Serious
> problem. While updating status, cannot find taskid
> attempt_200903241312_0074_r_000001_0
